And while the baseband IS updated in this firmware (so if you're yellowsn0w unlocked, DON'T upgrade til a proper PwnageTool version is out), 3.0 is already jailbroken, so say the Dev Team on a recent blog post.

And for those wondering, yes the 3.0 OS is jailbreakable on all devices. It’s just those using 3G yellowsn0w that have to show some restraint and wait for PwnageTool to create a custom IPSW that avoids the baseband update.

We'll let you know ASAP when a version of PwnageTool which works with 3.0 is out, but rest easy knowing the devices are already ready for WinterBoard and all your favorite jailbreak apps right next to Apple's 100 new 3.0 features.

Actually all your favorite jailbreak apps probably won't work, just like apps needed to be ported from 1.1.x to 2.0, apps will need to be ported from 2.x.x to 3.0, but this is good news! i was hoping to get the new iphone in the summer because I still have the first gen, but it could be unjailbreakable. We'll just have to wait and see. ^I guess this means the dev team has updated some of their phones to 3.0??
